/validate_plan thoughts/shared/plans/2026-03-08-my-feature.mdProcess
Section titled “Process”- Locate the plan — Uses the provided path or searches recent commits
- Gather evidence — Reviews git diffs, test results, and the current codebase state
- Check each criterion — Verifies every success criterion from the plan
- Report findings — Produces a validation report with pass/fail status for each criterion
- Identify issues — Flags any deviations, missing implementations, or regressions
When to Use
Section titled “When to Use”- After
/implement_plancompletes - Before creating a PR
- When reviewing someone else’s implementation of a plan
What This Adds
Section titled “What This Adds”The base tools don’t have a concept of verifying work against a spec. /validate_plan is instructed to be rigorous — it checks every success criterion from the plan, reports pass/fail per criterion, and gathers evidence from diffs, test results, and the current codebase state. It identifies deviations, missing implementations, and regressions rather than giving you a vague “looks good.”
